GRAIN-DOOR FOR CARS.

To all whom it may Concern:

Be it known that I, mrnn Sco'r'r Wn.- Luns, a citizen ot the UnitedStates, residing at Clinton, in the county of Dewitt and State ot'Illinois, have invented certain new and useful Improvements in(trani-Doors for Cars, of which the following is'a specitication.

My invention relates to the improvement of grain doors t'or cars and theobjects of my invention are to provide an improved construction ot doorsadapted for use in connection with cars carrying grain or othercommodities; to so construct my improved doors as to admit of theirbeing readily opened when they are subjected to the pressure ot' grainwithin the car; to provide improved ineans for locking the doors and forpreventing the escape of grain beneath or about the same; to. provide inconjunction therewith improved means for closing the upper portion ofthe car doorway and to so construct metallic or wooden doors for graincars as to permit ot their being easily and ireadily handled. Theseobjects I accomplish in the manner illustrated in the accompanyingdrawing, in which:

Figure l is a face view ot a car body showing my improved doors thereinin a closed position, Fig. 2 is an enlarged'section on line -m of Fig.I, Fig. 3 is an enlarged section on line y-y of Fig. l, Fig. I is anenlarged transverse section 011 line z-z ot' F ig.4 l, Fig. 5 anenlarged detail view in elevation illust ating the manner of hinging theinner door seetions,'and, Fig. G is a View of the base ot' one of saidhinges taken at right angles with that shown in Fig. 4..

Similar ntnneralsrefer to similar parts throughout the several Views.

l represents a car body and 2 one of the doorways thereof. v

3 represents a fixed door sill plate which is secured to the Hoor of acar and extends between the sides of the doorway in the inner portionthereof. To the outer edge of the plate 3 is hinged a second sill platemember 4, the latter when extended outward*7 lying in a recess 5 of thedoor ,entrance and terminating in a downturned flange 6 which engages anouter and second recess 7 which is formed in the outer face and upperportion of the wood sill of the doorway. It will thus be observedthatthe plates 2 and I form a Specification of Letters Patent.

complete'metal covering 'for the sill or entrance to the door.

IVithin the Icar and at each side of the doorway, I provide a fixedVertical hinge rod S each ot the latter having formed on its lower endan enlarged collar or boss E), the nppcrside o' which is provided inits'rear portion with a notch or recess 10. Mounted to swing upon eachot the rods S is a vertically disposed metallic door section 11 which ispreferably ot metal and to the outer vertical edges ot these doorsections are hinged as indicated at'. l2, outer door sectionsI I3. llachof the sections Il has its inner vertical edge portion shaped to form asubstantially tube-like hinge sleeve 1I through which the hinge rod 8passes loosely. The lower end of each o these hinge `sleeves is inclinedas indicated at let in Fig. 5, this inclined lower end being adapted toride upon the upper side of the corresponding boss collar i). ()ne ofthe door sections It has its outer edge portion provided with auoutwardly project-ing eX- tension or lip l'l which when the doorsections are extended, overlaps the outer edge of the opposite section13.

Iivoted to the outer side and lower portion o'tl each ot' the doorsections lil is one end ol' a depending latch plate l5, the lower end otthe latter normally extending below the lower end ot the door sectionwith which itI is connected and adapted to engage the outer side ol thevertical extension t5 of the sill plate member -lwhen the latter isturned upward and inward against the door sections, as shown in Figs. Iand 8 of the drawing. (lne otE the door sections I3 has pivotallyconnected therewith one end of a latch bar 1G, said latch bar beingadapted to be swung to the horizontal position shown in Fig. l of thedrawing and to have its otherwise tree end engage a Suitable catchprojection 1T on the outer face of the remaining door section 13.

As indicated in the drawing, the doox`- sections 11 and 13 have theirupper terminations at points below the top of the doorway or'franie andin order that the space above said door sections may be closed ifdesired, I provide an upper door horizontal section 1S which has itsupper edge portion suitably hinged on the inner side ot' the car abovethe doorway and which as indicated in Fig. 4

of the drawing, hns its end portions provided with transverse roundedextensions which ni :idnpted to-ene'nge or einhrziee the upper portionsot' the rods when snid door is in the lowered position shown iii tolllinesI in Figs. l :1nd 5).
